ABSTRACT
Based on the block diagonal preconditioners by Cao in the study [Zhi-Hao Cao, A note on block diagonal and constraint preconditioners for non-symmetric indefinite linear systems, International Journal of Computer Mathematics, 83(4) (2006):383-395], we present a new block diagonal preconditioners for non-symmetric indefinite linear system. Moreover, we analyses the properties of the corresponding preconditioned matrices.
